We examine wireless systems employing Rake receivers and fast scheduling over multiple users. The interactions between multipath diversity, multiuser diversity, and the feedback delay are investigated in terms of the mean signal-to-noise ratio (SNR). It is assumed that all users experience the same propagation characteristics, i.e., the same number of taps and power-delay profile (PDP). The result

The Augmented Reality (AR) concept has excited visionaries and researchers for decades, and finally its enabling technologies are beginning to materialize on consumer-grade mobile devices. The availability of powerful mobile computing platforms combined with fast mobile Internet access, opens the door to ‘solid’ visual/auditory augmentation of the world with geo-spatial knowledge, distilled from

Durable polymers functionalized with acidic or basic groups are currently developed for proton- or anion-exchange membrane (PEM or AEM) fuel cells, respectively. The properties of perfluorosulfinic acid PEMs restrict the conditions under which these fuel cells can be operated because of limitations conductivity and stability. We are presently pursuing different approaches to alternative membranes

Popular Abstract in SwedishDenna avhandling studerar relationer mellan film och historia. Tesen som drivs är följande: Film utgör ett i stora delar outnyttjat historiskt källmaterial som alltid säger mer av empiriskt värde om sin produktionskontext än det gör om perioden som skildras. Denna tes bygger vidare på resonemang kring film och historia som genom åren har framlagts av företrädesvis historThe hypothesis put forward in this thesis stipulates that films always say more of empirical value about the time in which they are produced than they do about the periods they depict. The aim is not only to prove that such an idea is valid, but also that it might be transformed into a new and applicable theory in studies of film and history. Here, this is done in contextualized analyses of the pr

Popular Abstract in Swedish Forskningsfokus i den här avhandlingen har varit framgång i säljande skapad i säljare och köparinteraktioner på och mellan makro-, meso- och mikronivå. Framgång har studerats som ett värde med konsekvenser för utbytesprocessen eftersom framgång påverkar aktörernas agerande i säljar- och köparinteraktionen på olika nivåer i företagen. Studien är avgränsad till framgång iThe research focus in this dissertation has been on success in selling as created in the seller and buyer interaction on and between macro-, meso- and micro levels. Success seen as a value has consequences for the exchange process, since it affects the actor's action in the seller and buyer interaction on different levels in companies. The study of value is limited to success in selling as a value

This study is concerned about the effects of brine discharge into the Arabian Gulf and desalination plants location also. The major concern is the Arabian coastline of the Gulf countries which started from Kuwait whole way to United Arab Emirates. Different scenarios for desalination plant and brine discharge management in the Arabian Gulf are discussed using mass balance computations. The Arabian
